PS4 launched in Japan on February 22 and as expected Sony's system and its launch titles have dominated the latest video game chart.

10 of the Japanese Top 20 are PS4 games, with bundled title Knack coming out on top with 309,304 units - the same as Media-Create's official PS4 hardware sales.

The best-selling non-bundled game was Yakuza: Ishin! with 82,540 units sold. Killzone: Shadow Fall managed 32,336 units, followed by Battlefield 4 with 24,799 units.

Other titles making the Top 20 include Dynasty Warriors 8 with Xtreme Legends, Assassin's Creed 4, Call of Duty: Ghosts, Tomb Raider: Definitive Edition, FIFA 14 and Need for Speed: Rivals.
